I haven’t looked around too much but I know PDX was over three degrees above average and about 0.7F shy of their warmest July on record. I think places down south in the Willamette valley were even warmer, especially with regard to average highs. But admittedly I haven’t found it interesting enough to do a lot of digging.

Don't have the final data yet for Battle Ground, but looks like #10-14 warmest there, and around 2.2F shy of warmest on record.

For downtown Portland, with current location records going back to 1972, it was also about 2.2F shy of warmest on record.

Eugene = 20th century Medford

EUG's warmest summer on record, 2015, was still about 2 degrees shy of Medford's 20th century average.

SLE ended up 10th for July. Sadly we have to count that as a win...

Felt like #13 kinda warmth out here, although my neighbor had an RV pad poured about a week ago and the difference is already palpable.

No hundos...max temp of 98 so far through July, which is lower than every year since 2013 except 2019, which had reached a peak of 97 at this point.

I’m getting the feeling that there will be a decent wind event this fall/winter. The past 3 ninos all had at least one decent windstorm IMBY. The one in early Jan 2019 was pretty big but I somehow didn’t lose power during that one. I haven’t lost power for more than a day since the windstorm in Oct 2014. There were multiple good windstorms that fall. The fall of 2015 was pretty good as well with the one in August and then there were multiple rounds in November of wind.

Kind of doubt we can make it through August without hitting the century mark, but if it happens it would be the first time since 2018 SLE goes through summer without hitting 100.

How about that 12Z ECMWF?   An actual front with rain next Wednesday.   This would be so nice for many reasons.

I figured we would see this pop up eventually after about 2/3 of the EPS members were showing a decent rain yesterday. 00Z was more like 50/50. Hopefully the 12Z ensembles are closer to that 2/3 rainy mark again.

Salem hit the century mark three times in 2008. Then it snowed. But it snowed more here.

We ended July this year with 0.10" which is pretty close to our decadal average. September is a month that has not been a complete loss in recent years, so I have some hope we can have some decent rainfall next month. In fact September 2019 and 2021 had about 3" of rain at SLE, which puts them in the top 15, and of course September 2013 blew away every other year with 7.05" blowing away the previous record of 4.84" from 1914. We had about 13" up here that month, almost doubling the previous monthly record. 

September will deliver this year.

Snowed a lot more at SLE than EUG though. Sorry TWL

In recent winters, RDD has gotten more snow than EUG.

Going to be camping in the Washington Cascades east of Chinook Pass for several days. Hoping to catch some thunderstorm action this weekend. If I do, I will not be posting about it real-time as I will be off the grid.

Is that actually true? I know it was last winter, but Eugene had 10.1" in December 2021 and 18.9" in February 2019.

Sadly the 12Z EPS backed off on the rain (~1/3 of members with > 0.1" at KSEA in that time period), so the friendly deterministic run will probably back off in the next cycle.

Idk about EUG because of Feb 2019. But yes, Redding, despite having 100°F average July highs and date palms, has gotten more snow than some parts of the Willamette Valley in the last five winters. Pretty sure they’ve got Corvallis beat.

I was so pissed when they got 8” this Feb lmao

[Cloud]

OLM +1.1

BFI +1.3

SEA +1.4

PAE +2.4

All things considered, I’d say a reasonable July for W. WA. PAE is the warmer spot but they never hit 90. 87 was warmest day.

OLM, SEA, and BFI all ended the month with 8 consecutive negative departure days.

They did really well during the Snowpocalypse too.

I remember we discussed how much easier it will be to get colder than normal days and months after the 1991-2020 update with the averages jumping up.    And we are still increasing those averages by coming in even warmer.  

[TT-SEA]

From 1945-2012 there were just 3 years with a July as warm as this year at SEA... 1958, 1985, and 2009.    Since 2013 this July was pretty much normal.

12 Julys from 1945-2012 were warmer at OLM.

The update to 1991-2020 normals was a much bigger deal for SEA than OLM.

The 2013-2022 average for July at SEA was 68.46.     This July finished at 68.50.    Right in line with the last decade.

Like I've said, a July like 2001 might as well be the 1950s or 1850s at this point. That version of our climo is gone and not coming back anytime soon. 

Even the deified air around OLM hasn't come within two degrees of that July since 2011.

Made it down to 49 this morning again.

Looks like SEA will end up at 80+ today.

83 here currently.

I agree completely. I feel like what we saw this July was essentially normal for our current climo.

Starting out august right. By breaking the sub-80 streak.

2-25-19 & that 72 hour stretch was the 2nd snowiest in the books I believe. Only Wine Dine ‘69 Big Snow was bigger which was an Arctic blizzard that dropped 3 feet like a poor-man’s Buffalo, NY.

That event was so damaging in rural Douglas County at Loon Lake that the campground would not re-open until mid-summer 2022. 

[SilverFallsAndrew]

That was quite the event. Places in Central Oregon  had 2-3' of snow, we had a two day total around 11" I believe, but were a bit north of the main action.

If you used 2013-2023 as the average… PDX would actually classify as a “hot-summer Mediterranean climate” per the Köppen system.

Portland = southern Spain and Greece!!!

BAM! 90F

Thankfully, no such trend for the cold season. 

2000-present, I mean.
